Trochoidal Milling Due to the trochoidal milling process, large depths of cut are also possible on unstable and weak machines. Depending on the tensile strength of the material, the radial infeed is 5–20% of the cutting edge diameter. As trochoidal milling is a plain milling process, the forces that occur are lower. When trochoidal milling a slot, the milling cutter diameter should be a maximum of 70% of the slot width. Example: Slot 20 mm x 70% = 14 mm A Ø 14 mm milling cutter would be the perfect tool.

Our recommendations for this application are as follows: Please note that the indicated values may require reducing due to the component design, machine rigidity and machine dynamics. In optimal conditions, the values can also be increased. Solid carbide milling cutters Technical Information
